Doctoring systems
The proper design and application of a doctoring
system can improve the performance of your
paper machine.
BONETTI doctoring systems, are
custom
designed to meet the deflection and natural
frequency requirements for a particular machine
width, speed and roll diameter.
Engineering at BONETTI is supported by the
most advanced software available on the market.
We perform finite element analysis (FEA) to
accurately model our products to determine
structural integrity, performance and reliability,
as well as predict structural failures.

Established in 1923 Bonetti has been
successfully supplying the pulp and
paper industry since more than 50 years.
The renown reliability and quality of coater
blades gave rise to the first requests
for doctor and creping steel blades
in the late 1960’s. Synthetic-material
doctor blades became available in the
1980’s. Challenged by ever-changing
doctoring technology, Bonetti has
then successfully developed “hi-tech”
materials to meet specific Customer
needs. In the mid-1990’s Doctoring
and Creping Systems were a natural
addition to the Bonetti Product lines.
High-quality Doctor Holders, Systems
and Spare Parts, with innovative design
features have since been manufactured
and installed throughout the world. To
meet worldwide product demands, four
(4) new manufacturing facilities were
inaugurated in the 1990’s and 2000.
Sturtevant, WI USA; Hagen, Germany;
Cantalupo, Italy; Trois-Rivieres, QC
Canada; now complement world
headquarters in Lainate, near Milan
in Italy. Bonetti’s success has always
been based on a timely response to the
needs and demands of the markets it
serves. For more than 50 years, and
now in the third generation of family
ownership, Bonetti has been and will
continue to be a global partner of paper
mills and paper-machine manufacturers
worldwide.
